Apparently a couple of brewers made 20 gallons over several batches that soured and were drain pours. Turns out the LHBS sold them citric acid instead of priming sugar. https://www.reddit.com/r/Homebrewin..._been_having_issues_with_sour_beer_found_the/
Definitely a shitty experience! They should of made a small batch until they figured out their problem!!!!!
I hope they were comped a couple bags of base malt. I wonder how many other homebrewers were fuct by that mix up.
Or you could just use table sugar. Cheaper, and does the job just as well. That's not to say that this isn't a huge mix-up, and some DME or basemalt should definitely be comped.
Yea, I actually used table and brown sugar on every bottled batch this year. Much easier to come by too, since it's always sitting in my cupboard. I agree though, I'd be pretty pissed if I got citric acid in a batch that I spent hard work, time and money on!
